Servo Press Wikipedia

Aida servo presses and mechanical stamping presses range in capacity from 30 to 4000 tons from 1 to 1500 strokes per minute from gap frame to straightside high speed to cold forging transfer and progressive die. A stamping press is a machine press used to shape or cut metal by deforming it with a die.

Servo press wikipedia. It generally consists of a press frame a bolster plate and a ram. This drive system combines the simplicity of the original clutch and brake technology with the speed of a hydraulic ram driven system. An electrohydraulic servo valve ehsv is an electrically operated valve that controls how hydraulic fluid is sent to an actuatorservo valves are often used to control powerful hydraulic cylinders with a very small electrical signal. It consists of a suitable motor coupled to a sensor for position feedback. Aida dsf series servo presses are the most advanced servo stamping presses available. A servo drive turret punch press uses twin ac servo drives directly coupled to the drive shaft. Aida is a global leader in the design manufacture sale service and support refurbishment and modernization of metal stamping presses and metalforming automation equipment. Servo systems can be used in cnc machining factory automation and robotics among other uses. A global leader in the design and manufacture of high speed servo feeding systems vamco products are available to be paired with all press brands and are ideal for high speed and lamination applications. Servo electric brakes use a servo motor to drive a ballscrew or belt drive to exert tonnage on the ram. This assembly may in turn form part of another servomechanism. Pneumatic presses utilize air pressure to develop tonnage on the ram. An example of peculiar press control. Hydraulic presses operate by means of two synchronized hydraulic cylinders on the c frames moving the upper beam. It also requires a relatively sophisticated controller often a dedicated module designed specifically for use with servomotors.

Servo drive turret punch press. A potentiometer provides a simple analog signal to indicate position while an encoder provides position and usually speed feedback which by the use of a pid controller allow more precise control of position. Servo valves can provide precise control of position velocity pressure and force with good post movement damping characteristics. Aida was the first and is the industry leader in direct drive servo presses. Capping presses form caps from rolls of aluminium foil at up to 660 per minute. A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position velocity and acceleration. A servomotor is a specific type of motor that is combined with a rotary encoder or a potentiometer to form a servomechanism. Aida servo presses cover the widest range of capacities and capabilities available from any press manufacturer from 80 through 3500 metric tons. Their main advantage over traditional dc or ac motors is the addition of motor feedback. This feedback can be used to detect unwanted motion or to ensure the accuracy of the commanded motion.
